摘要
针对移动多媒体业务的迅速发展,中国提出了具有自主知识产权的中国移动多媒体广播(CMMB)系统。本文研究CMMB系统中接收端对视频广播业务的解复用和同步播放,并提出实现方案。针对在嵌入式硬件平台上对方案进行研究的高成本和高复杂度的问题,在PC平台上实现软件解复用器和播放器。实验结果表明,该方案很好地对复用码流中的电视业务实现了解复用和同步播放。
For the rapid development of mobile multimedia services, China has proposed a CMMB system with independent intel- lectual property rights. This paper researches the de-multiplexing and synchronous playback of video broadcasting services on re- ceiving end in CMMB, and proposes an implementation scheme. In general, embedded hardware platform has the problems of high cost and high complexity to study the scheme, so we implements the software of de-multiplexer and player on PC platform. The experimental results show that this scheme does well for TV business stored in stream.
